+In general, Lynx translates letters from document charset to display charset.
+If document charset is not specified or not recognized by Lynx, we fall back
+to different assumptions below, read also lynx.cfg for info.
+
+UCLYhndl_for_unspec -  assume this as charset for documents that don't
+                       specify a charset parameter in HTTP headers or via META
+                       this corresponds to "assume_charset"
+
+UCLYhndl_HTFile_for_unspec -  assume this as charset of local file
+                       this corresponds to "assume_local_charset"
+
+UCLYhndl_for_unrec  -  in case a charset parameter is not recognized;
+                       this corresponds to "assume_unrec_charset"
+
+UCLYhndl_HTFile_for_unrec  - the same but only for local files,
+                             currently not used.
+
+current_char_set  -	this corresponds to "display charset",
+			declared in LYCharSets.c and really important.
+
+All external charset information is available in so called MIME format.
+For internal needs Lynx uses charset handlers as integers
+from UCGetLYhndl_byMIME().  However, there is no way to recover
+from user's error in configuration file lynx.cfg or command line switches,
+those unrecognized MIME names are assumed as LATIN1 (via safeUCGetLYhndl...).
